Hitachi unveils RFID powder
How can they tell which bits of the dust stick to the target in question though? Say someone gets it in their hair and some of it gets blown away. Then ypu get signals going in different directions, with no way of knowing which is the one you want to follow.
Lol, my thread.
Why mark your suspect's car with a tracking device or surprise him with a dart to the neck (http://science.slashdot.org/article.pl?sid=04/04/12/1745241&mode=nested&tid=126&tid=158&tid=99) when you can just blow some magic tracking dust into his face?

A few weeks ago, Japanese tech company Hitachi beat its own internal records by developing an RFID chip 64 times smaller than their previous best, the mu-chip. For an idea of the sizes involved, the mu-chip is the black speck on the finger in the left-hand picture. The RFID dust is on the right. Next to a human hair. :eek:
Weighing in at a dainty 5 microns, these new chips are small enough to be embedded easily in paper or *ulp* human skin. Possible applications include anti-counterfeiting measures, security chips to track important documents, and *ahem* THE ENSLAVEMENT OF THE HUMAN RACE.
*cough* Yeah, anyway...
So, what do you think will happen if prices come down and RFID dust becomes as common as... well... dust? What could billions of invisible 128-bit chips do?

wow thats cool
what range does it have?
it must be a bit pricey to dust a stranger with hundreds of them.
are they supposing that something that small has enough power to generate a gps tracking signal all by itself? what powers it?
I think it would be used more as a passive rather than an active signal -- authorization and validation rather than tracking. The hyperbole was all me. :p
Still... there's something creepy about a microchip you can inject into your bloodstream...
Or snort a line of microchips.....

the site shows a gps output indicating where the tagged person is in the world.
i think they are taking the piss.

It's sort of an antenna... A signal is broadcast towards the chip, it picks it up, uses it to power the chip that does its work and then broadcasts its own signal which can be detected by the original transmitter/receiver.
Like old wireless radios, it's powered by the radio waves themselves; batteries not included.

I think it's time to stock up anti-RFID devices before they become illegal!

yeah thats my understanding of how rfid works and why its not worth the paranoia of the anti-rfid crowd
but something that small inside the body couldnt possibly have much of a range. im thinking that it could be used in a bond movie to tag "the jackal" so that as bond passes through the crowd he could identify the bad guy no matter how completely disguised he is.

*Snort* Huh? What was that? Oops.
